Lupita Nyong'o may be one of Hollywood's most famous women these days, but she hasn't quite gotten used to it yet. The 12 Years A Slave award-winning actress confessed to Stephen Colbert on The Late Show last night that her meteoric rise has been "shell-shocking." "I've had a hard time adjusting to it, for sure," she told the host. "It's strange that people know how to pronounce my name, for example." Nyong'o also noted that it took some time for her to get over what she refers to as "acute imposter syndrome" — which amounts to, as she described, the feeling that you have everybody fooled when you're succeeding at something. If she's still feeling like she's faking it, Nyong'o is certainly fooling us: She's seems unbelievably comfortable and confident during the conversation about her craft, current projects, and whatever comes down the pipeline. The actress even admitted that — despite having starred in roles with major gravity — she would consider doing silly comedy, too, if the right part arrived. "Comedy is very scary. And I like to be scared," she told Colbert, who then asked her if she liked to be embarrassed. It seems like the only two people in the world who would answer "yes" to that question were on the stage last night — and they both decided to prove it. Apparently, when Nyong'o was less recognizable, she would do weird walks down the street. She reprised this silliness on the show, performing a walk across the stage as a "paranoid person whose pants are falling down." How this woman managed to accomplish this walk in heels and still leave us feeling like she's the most graceful gal ever is beyond us. And yet, somehow, it happened. See for yourself.
